EDMUND S. CHURCH, OF DAYTON, OHIO, ASSIGNOR TO THE NATIONAL CASH REGISTER COMPANY, OF DAYTON, OHIO, A CORPORATION OF OHIO, (INCORPORATED IN 1906.)

CASH AND CREDIT REGISTER.

Specification of Letters Patent.

Patented May 16, 1916.

To all whom it may concern Be it known that I, EDMUND S. CHURCH,

a citizen of the United States, residing at- Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash and Credit Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to cash registers 'andmore particularly to cash registers which are adapted to operate and be operated by detachable accumulating and accounting devices.

Among the objects of the invention are to provide improved means for locking the detachable accounting? devices in the register and unlocking and ecting the same.

Another object of the invention is to provide an improved actuator for totalizing de vices. which actuator is capable of an extra unit of movement either in an additive or subtractive sense, for the purpose of carrying transfers from one totalizer pinion to another.

Another object of the invention is to pro vide an improved cam selecting device whereby different cams may be operatively connected with a totalizer operating mechanism for the purpose of'causing a totalizer to be diflerentially rotated and then returned to its zero position, or to be dilferentially rotated either in an additive or subtractive sense.

Another object of the invention is to provide an improved means for transmitting differential settings of the detachable accounting devices to totalizing devices of the machine.

Another object of the invention is to provide an improved printing device. including a printing cylinder which may be automatically adjusted upon successive operations of the machine to print different matter, such as advertisements, upon checks which are. issued by the printing device.

Another object of the invention is to provide improved ink ribbon carrying devices with improved means for reversing the direction of feed .of the ink ribbon.

With these and incidental objects in view the invention consists of certain novel features of construction and combinations of parts the essential elements of which are set forth in appended claims and the pre ferred form of embodiment of which is hereinafter described with reference to the draW- ings which accompany and form part of the specification.

Fig. 21 is a detail side elevation of .one of the subtotaliZer actuators and transsubtotalizer and from the latter back i detachable device. Fig. 23 is a front ele'ation of the devices under the control of special bank of keys for shifting the cams which determine the time of engagement be tween the actuators and subtotalizer. Figs. 24 and 25 are detail views of the cams and connections for engaging the actuators and subtotalizer during the coding and subtracting operations respectively.

The cash register of the present invention is of the same class as the register which is described in a copending United States patent application, filed by 1B. :5. Church on Jan. 17, 1910, Serial l lo. 538,170, for cash and credit register.

The register is adapted to be controlled by and differentially to detachable accounting devices. These devices comprise a. plurality of denominational slides which may be adjusted by the reg to represent different amounts and t en be locked in their set positions and ejected from the register. A record. is thereby preserved in the detachable accounting device which may againbe transferred to the cash register by inserting the detachable accounting device in an opening of the register provided for this purpose. l l hen a detachable accounting device is inserted in the register its denomination slides engage coacting slides in the register and thereby diiikarentiall Y position the slides of the register according to the positions of theslides of the detachable accounting device The register contains a subtotalizer which receives dii'i erential rotation from the detachable accoi'inting device and then is further actuated either in an additive or subtractive sense by controlling devices of the register. Means are provided for resetting the subtotal'izer and trans ferring its final setting to the detachable accounting device, which is then eject-ed from the machine in its newly adjusted condition. The actuating mechanism for the subtotalizer consists of a plurality of racks which are carried by ditlerentially movable members and which are arranged to move for transferring purposes an extra unit under spring action relatively to their carrying devices, in either an additive or subtractive direction. I

Driving mcchamlcm.l'iaving reference shown in Fig. 2. This carria is slidablc on a plate 2 and within guide plates 3 pro vided with horizontally di osed guide slots 4 through which extend pll'ls 5 on the carriage 1. Rods 6 are carried by lugs T of the plates 3 and extend through holes in. the pins Coiled springs 8 r-au'round the rods 6 and are adapted to be compressed between the lugs 7 and the pins 5 upon inward move-- incnt of the carriage l for the purp 1 se of returning the carriage at the completion of each operation of the n'iachinc.

Upon the insertion of a detachable accounting device it becomes auton'iatically locked to the machine, and unlocks a. banli of special keys so that these keys may be manipulated; depressionppecial he prevents release oi. a detachable device during the operation oi the mat-hin though a detacl'ial'ilc device may brrcloascd and ejected from the machin if (h d, before the depression oi a special or iransactimi key. A. manipulative device is provided which may be adjusted lo cause he detach able devices to be ejected aitor each opera-- tion of the machine, or may be adjurfied so that the detachable devices will not be automatically ejected but may be snc ssivoly operated by contii'iucd operation of the ma chine. The follmving description relates to these latching and locking devices: The carriage 1 is moved inwardly nmnually upon the inscrtion of a detachable accounting dcvice through engagement with FOLWVHITlGllLl fl (Fig. 3) of the ammunti, device. The detachable :\(.('.()l.l]']l'lll{1' dcvi: are provided with shouldered blades 10 Wii when the accounting devices are insertei'l in an opening 11 of the regriclcr ongragijc a late-h 12 Figs. 2 and 20.011 the carriage l. rocking; the latch 12 upwardly around its pivot 1 until a shoulder ll 'l the blade 10 passes the shoulder of the latcln when the latch drops downward slightly thus bringing a roar \ard extension 15 o1 an arm iii, which is secured to the pivot pin 13, into a horizonlal plane with anopeniug 1'2 of a bracket 15%.

The continued rearward movement of the detachable accounting device and the carriage 1 causes the rearward extension 15 to enter the opening 17 thereby preventing the release of the accounting device from the carriage l. carriage 1 brings a pin 19 on the arm 16 to the rear of a shoulder 20 of a latch 21 which is loosely pivoted upon a shaft he shoulder 20 then engages the pin 1- and prevents the withdrawal of the detachable ac counting device. The inward movement of the carriage 1 also causes the extension 15 of the arm 16 to engage an arm which is carried rigidly by the shaft rocking it rearwardly against the action of its S'Pllllg 24. The shaft 22 also carries a hook 25 which at this time-raisesclear of a pin- 26 carried by an arm 27 fast on a shaft 28. This shaft carries rigidly an arm 29 which extends below a key detent 30 of a bank of special keys 31. Upon the depression of a special key the detent 30 is moved downwardly a slight distance thus causing the shaft 28 to be slightly rocked, but if the hook 25 is not clear of the pin 26 it is impossible to depress a special key as the detent 30 is then prevented from moving downwardly.

Because of this arrangement it is impossible to depress a special or-transaction key unless a detachable accounting deviceis properly placed within the machine. The present machine is arranged similarly to other cash registers in respect to its bank of transaction keys, that is, it is impossible to operate the machine until one of the transaction keys is depressed. As machine locks under the control of transaction keys are common to a great many cash registers, one being shown in the application before referred to, a lock of this class is not illustrated in the drawings.

The lowering of the key detent 30 also causes a flange 32 of an arm 33, which is carried rigidly by the shaft 28, to enter one of two notches 3a and 35 in a slide 3(l'the reby preventing'movement of this slide during the time a transaction key is depressed and the machineis operating. The slide 36 controls means for lifting the latch 21 upwardly from its pivot 22 and thus releasing the carriage 1 and permitting the ejection of the detachable accounting device under the action of the springs 8. The slide-36 for this purpose carries a push key 37 extending outside the casing which, when pushed inwardly manually, causes the slide to move inwardly, an inclined edge 38 of the slide at this time engaging a pin 89 on the latch 21 thereby causingthe latch to rise and release the carriage 1 But manipulation of the key 37 is prevented by the flange 32 whenever a transaction key is in its depressed position. The key 37 and slide 20 are shown in their normal position in Fig. 2. The key 37 may also be pulled outwardly a slight distance bringing a shoulder 40 on the slide 36 over the pin 39 and the notch 3% of the slide in the path of movement of the flange The slide is then similarly locked upon the depression of a. transaction key but when it is in this outer position the shoulder 4.0 prevents the actuationot the latch 21 and thereby prevents the usual release of the carriage 1 by certain operating mechanism for-this latch, which is under the control of the driving mechanism of the register and is arranged norx'nally to release the 7 carriage 1 at the completion of the operation of the machine. Therefore when the key 37 is in its outer position it is not necessary ever, be rocked forwardly position by drawing the key 3, engage setting slides or racks to reinsert a detachable accounting device if it is desired successively to make several registrations in the same; however at the completion of any operation of the machine the detachable accounting device may be released by pushing the key 37 inwardly its full movement.

A cam for automatically lifting the latch 21 at the completion of operations of the machine and when the key 37 is in its normal position, is illustrated in Fig. a. This cam 41 actuates a pitman 42 which is connected at its lower end (Figs. 2 and 20) to a lever 13 which is pivoted upon the shaft'22 and at its forward end carries a rocking member sat by a pivot carried by the latch 21, extends through. a slot 46 in the member 44 and whichis circular to its pivot 47. The member 4a is shown in its normal position in Figs. 2 and 20 and when in this position the downward movement of the pitman +l2 all to lift the latch 21 and thereby release the carriage l.

The member 44 may, howfrom its pivot +1.7 bringing a radial off-set part 48 of the slot 46 beneath the pin and when in such position the upward movement of the mem ber ll does not cause the release of the carriage 1. The member 4-4 is set in this latter 37 outwardly above the pin prevents upso that the shoulder 71*0 comes 39 of the latch and positively ward movement of member 414 and thereby the release of the carriage 1. In order that the key 37 may control the angular positionmg of member 44, this member is provided with a pin '49 which extends through a slot 50 in the slide 36.

Difcrenzfial mccham'sm.l/Vhen a detachable accounting device is inserted into the machine its denominational blades 51, Fig. 52 (Figs. 2. (l and 22) which are slidably mounted with in the machine. These racks are moved inwardly more or less according to the setting of the denominational blades of the detachable device. If a blade .51 is in its outer or nine position it will cause its respective coacting rack 52 to move nine units of movement, whereas if it is in its inner or zero position it will not disturbthe setting of its respective rack 52 upon the inward movement of the detachable device.

T he racks 52 mesh with intermediate pinions 53 (Figs. 6 and each of which is pinned to a: slide 54 and meshes with teeth of an actuating slide or rack bar 56.

pin 4.7. A pin 45, which iscauses the member fore when the racks 52 are difiere'ntially pushed inwardly they cause the gears 53 to roll rearwardly upon the rack teeth 55 and thereby carry their slides 54 rearwardly more or less depending upon the extent of movement of the setting racks 52. The slides 54 are slidably mounted upon a rod 61 and a shaft 62 as indicated in Figs. 6 and 22, and when moved rearwardly bring their rear edges 63 more or less toward pins 64 which are carried by arms 65 fast on a shaft 66, there being one pin and arm for each slide 54. This shaft is oscillated by a cam 67 (Fig. 9) for the purpose of restoring all of the slides 54 to their zero positions, but before the slides 5e are restored pawls 68 are rocked downwardly into mesh with teeth 69 in the racks 52 thereby'locking the racks 52 in their moved positions; then when the slides 54 are restored the gears 53 roll upon teeth of the racks 52 thereby causing the actuating racks 56 to move forwardly extents which correspond to the original inward movement of the racks 52. No means for rocking pawls 68 are shown but it will be understood that this is accomplished by a cam on one of the drive shafts, connected to the pawl supporting shaft, this cam to retain the slides 52 locked from the very beginning until nearly the'end of the operation of the machine. The racks 56 are provided with rackteeth 70 which mesh with segment gears 71. The segment gears 71 are loosely journaled on shaft 62 and are secured to segments 72 which carry racks 7 3 meshing with idle pinions 74 (Fig. 11) which are journaled upon a subtotalizer shaft 75. ions 76 (Figs. 6 and 22) are also journaled upon the shaft beside the idle pinions 74 and may be operatively connected with the idle pinions by broad pinions 77, Figs. 11 and 12, which are journaled upon a rod 78 of a frame 79 which is pivotally hung from a shaft'80. The broad pinions are normally out of mesh and during the restoring of the slides 54 remain in this position, therefore the rearward movement of the segments 72 merely cause the idle pinions 74 to be differentially rotated according to the extents of rearward movement of the segments. -When the segments 72 are at rest in their moved positions the broad pinions 77 are rocked into mesh with the pairs of pinions 74 and n, and are held in mesh during the return of the segments 72 to their zero positions and thus cause the differential rotation'of the totalizer pinions inexact correspondence with the extents of inward movement of the racks 52. The se ments 72 are restored to zero positions by a cam 81 (Figs. 8 and 22) on drive shaft 92. This cam acts upon a roller 83 on a pitman 84 which connects the cam to an arm 85 (Fig.7) fast on a shaft 86. Shaft 86 car- Subtotalizer pinries a pair of arms 87 between which extends a rod 88 passing across the front edge of the lever arms 58. ranged to rock the rod 88 forwardly when the rack bars 56 are moved forwardly but when these rack bars and the segments 72 are at rest in their moved positions the rod 88 is returned to its original position as shown in Figs. 8 and 22, thereby restoring all of the racks 56 to zero position. and through these racks restoring the seg* ments 7 2.

The next operation which occurs is the unlocking of the denominational slides of the detachable accounting device in the machine. In order to unlock these slides it is necessaryto rock a locking plate 93 (Fig. in the detachable device upon its pivot 9% in order to carry a flange 95 of the same out of engagement with the teeth 96 of the denominational slides 51. This plate is provided with a pointed flange 95 for the purpose of locking the slides in their set positions and extends beyond its pivot 94: be neath' an opening 246 in the casing of the dctachable accounting device. The machine is provided with an arm 247 (Figs. 2 and 20) which is pointed for the purpose of entering the opening 246 and rocking the plate 93 to its unlocking position. The arm 2&7 is actuated at the desired. time by a cam 248 (Fig. 5} which is carried by the drive shaft 92. This cam acts upon a roll 249 on an arm 250 which is carried by a sleeve 251 (Fig. 2) encircling shaft 111. This sleeve carries an arm 252 which is connected by a link 253 with an arm 254: on a, shaft 255 which carries the pointed arm 247, Therefore when the lever 250 is rocked downwardly by the cam 248 the lever 247 will be caused to enter the detachable accounting device which is in the machine and unlock the same. As the accumulating blades of the detachable accounting device are now free toimove, these blades will not interfere with'free movement of the differential mechanism of the machine whcn under the control of the keyboard. After the setting of the detachable accounting device has been transferred to v the to-talizer 7 6 the amount which has been set on the keyboard is either added to or subtracted from the totalizer depending upon which transaction key is depressed.

Amount keys 97 (Fig. 11) of which there may be several banks control thedflterential movement of a plurality of slides 98 which are actuated by springs 99 but are normally prevented from moving downwardly under the action of these springs by arms 100 fast on a shaft 101. This shaft is permitted to rock at the proper time to carry the arms 100 downwardly by a cam 102 (Fig. 10) which actuates a pitman 103 connected at its upper end to anarm 104 fast on the shaft 101. The slides 98 are cut, as indicated in The cam 81 is arlot
